Benefits of technology
The present invention proposes an optical analysis device that uses a multi-light source structure to overcome the limitation of conventional devices and measure a larger area. The technical effect of this device is to provide more accurate and reliable data on large measurement areas.
Problems solved by technology
However, when an amount of a measurement sample is increased, reaction light reaches a saturation state, and thus additional process of physically decreasing an optical path length is required for measuring a high concentration.
Accordingly, a measurement range is limited (narrow) when using a measurement device using a single optical path length.
However, in a case of a minute current, a measurable limit value becomes small even though the signal is amplified since a signal-to-noise ratio of the measured signal is small.
However, when using a single light source, a measurement range may be adjusted but adjusting an amount of light is limited.

The present invention relates to an optical analysis device using a multi-light source structure, which allows acquisition of an optimized measurement result by adjusting the number of light sources depending on a concentration of an object to be measured, such as ocean spilled oil, etc., and a method therefor. The optical analysis device using a multi-light source structure may comprise: a multi-light source unit including multiple light source units each having a light source which is selectively illuminated, in order to adjust an amount of light depending on a concentration of an object to be measured; a cuvette unit including a cuvette in which an object to be measured is disposed, wherein the cuvette has a prism shape and has as many faces as the number of the light source units plus one, the light source units faces the faces, respectively, and reactive light generated from the object to be measured is emitted through the remaining one face; a light sensor unit for detecting the reactive light emitted through the cuvette; and a control unit for controlling illumination of the light source units configuring the multi-light source unit.
